AURUNA® 311 For Technical Applications Gold Cobalt Electrolyte
For the adhesive direct gold-plating of stainless steel and nickel
AURUNA® 311 For Technical Applications is a strongly acidic alloy electrolyte for the adhesive direct gold-plating of stainless steel. It is preferably used for chromium-nickel steels, molybdenum steels and nickelbased alloys difficult to activate. Due to its strong activation effect, the electrolyte can be often used successfully as well for other passive materials difficult to plate.
The gold electrolyte is suitable for both strike gold layers and thick coatings in the technical field. The coatings are ductile, low in pores and protect against corrosion.
AURUNA® 311 For Technical Applications can be used for rack and barrel operation as well as in reel-to-reel plating (e.g. spray and dip cells and brush).
